Before You Begin
• Determine the appropriate installation location for the
thermostat
The thermostat must not be installed near or on
metal structures or surfaces including metal air
ducting that may be in the wall.
0HWDOVWUXFWXUHVDQGVXUIDFHVVLJQL¿FDQWO\
reduce the range of the wireless signal.
A. Refer to the Zoneline Owner’s Manual to enable the
use of a wall thermostat. For AZ45/65 Series Models,
auxiliary mode 6 should be set to “6A”.
B. Zoneline output is 24VAC. Be sure the jumper on the
wireless control card is on the AC position – jumper
is connecting “R” and “C” (common) pins. This is the
default position.

NETWORK INSTALLATION ONLY
NOTE: This section is not required unless the thermostats are
networked
Pairing the Thermostat and the Control Card:
In case of Network Installation with online management, the
thermostat and the Control Card must be paired with a Network
Programmer specific to the property before the installation.
Note: Thermostat and Control Card are factory paired.
The thermostat and control card must not be powered during the
pairing procedure - remove batteries from the thermostat and unplug
the control card from the HVAC unit during the pairing procedure.
• Plug one programmer connector into the thermostat;
• Plug the other programmer connector into the control card.
• Push the black button on the programmer.
• The red light on the programmer should turn on and remain
steadily lit.
• If the red light on the programmer is blinking or is not steadily
lit, unplug the programmer from the thermostat and the control
card and repeat the steps above.
• Unplug the programmer from the thermostat and the control card.

Thermostat Installation
Installing the Wireless Control Card (cont.)
• Using double sided tape, attach the control card to the Zoneline
control box cover (see image 2).
The wireless control card antenna must not be touching any metal
components of the hvac unit.
The wireless control card antenna must face the thermostat on the
wall and be oriented so that any metal parts of the Zoneline do not
obstruct the wireless communication to the thermostat and, in case of
a network installation, to other wireless control cards and the server.
The wireless control card must not be placed in the Zoneline
condensation pan and must be mounted so it cannot fall into the
condensation pan.
• For wired applications, join the common and 24VAC wires with
any code-approved low voltage field supplied connection method.
